This invention relates to looped pile rugs. In the general art of rug making, diiculty has always been encountered because of the desire for largersizes than is possible to weave or manufacture on conventional machinery. Thus, for example, in the conventional looped pile rug, machinery is available which will conveniently form a strip only approximately 36 incheswide. As a consequence, when wider Widths are required, it is necessary to join two or more strips. rlhis join- -ing procedure has generally taken the form of a 'strapped butt joint, in which a, strip of material yis glued or otherwise securedfto the backing sheet along the underside of the abutting edges. Glass or plastic tape has ordinarily been employed for this purpose.

For some types of construction, this has been fairlysatisfactory, but in other instances, it produced an unsightly and clearly visible joint. This was particularly true where as in the case of y looped pile rugs, the pile or loops were grouped in a series of parallel rows, spaced from one another approximately one fourth of an inch. The best solution in the art was to trim theedges of the backing sheets as close as possible to a line of pile in order that when two strips were brought edge to edge, the pile would tend to overlap and cover up the seam. 1

The present invention has been designed to overcome these difliculties by leaving a relatively wide marginal portion along one edge of the backing sheet, which strip is Without loops or pile. The other edge is conventionally formed with a line of pile secured in the strip as closely as possible to this latter edge, and preferably, this other edge is formed with a shorter pile. Thus, when` two strips are brought together, the wide unlooped edge is joined to an edge having the loops closely adjacent. They are joined by positioning the more conventional edge over the marginal portion of the adjoining edge in a lapped joint. A suitable adhesive such as latex is used to secure the same together and after gluing, the same may be passed through pressure rollers to improve the attachment. As a consequence, an excellent joint is produced which can be formed easily and inexpensively.

Thus one of the objects of the present invention is a looped pile rug formed of strips of material which present a uniform appearance on the upper side,the joints being practically invisible.

Another object of the invention is a loopedY pile rug formed of strips having joints which are essentially invisible from the upper side.

A further object of the invention is a looped 2 Claims. (C1. 2--278) pile rug formed of/strips in which one edge of each strip containing no pile is used to form a lapping joint with a piled edge of an adjoining strip.

Yet another object of the invention is a looped pile rug formed of strips of material utilizing a portion of the backing strip to form a lapped joint.

An even further object of the invention is a looped pile rug formed of strips of material joined together in a lapped joint.

And still another object of the invention is a looped pile rug formed of strips having a marginal portion with shorter pile.

In the drawings:

Fig. l is a plan View of a rug illustrating the preferred form of the invention.

Fig. 2 is a partial end view of a rug utilizing the preferred form of the invention, showing in detail the joinder of the strips.

In general, the invention is concerned with a llooped. pile rug which is exceedingly easy to manufacture and whose seams are substantially invisible.

Two factors contribute to this effect. One is obtained by leaving a margnalportion of each strip free of pile, so that another strip of material may be placed in overlapped position on .the marginal portion. The other factor `is obtained by utilizing a, shorter pile on the overlapping portion.

The preferred form of rug is illustrated in the drawings, but it is to be clearly understood that the form shown is illustrative only and other and various forms will be obvious to those skilled in the art.

The preferred form shown comprises a plurality of strips of backing sheet material I which may be canvass, duck or any suitable material. Secured to each strip of backing sheet material is a series of rows 2 of pile. The pile is preferably secured to the sheets I by forcing one or more strands or tufts 3 0f the pile material, which may be wool, cotton, etc., through the sheets so that they extend above the surface thereof a suitable distance. In the example, a looped cotton pile is illustrated and each tuft 3 comprises approximately three strands of cotton material.

In the ordinary case, the thickness of the backing sheets I may be of the order of 1,64 inch and the tufts or loops may be approximately 1/2 inch long or high, and spaced in rows approximately 1A, inch apart.

The description above is applicable to conventional construction. The invention is concerned 3 with a marginal portion 4 along one edge of the strips I, which, in practice may be of the order of 1-11/2 inches wide. As can be seen in Fig. 2, this permits the opposite edge of a similar strip l of material to be joined to it in overlapped position. In this position, the several outer rows 2A of pile on the uppermost strip will overlie the marginal portion 4l of the adjacent strip. The edge ofthe uppermost strip is positioned closely adjacent the row 2B of pile next to the marginal portion on the undermost strip in a manner that the adjacent rows 2 of pile on the adjacent strips. are spaced apart a distance approximately equal to the spacing of the rows.

The two strips are joined along this marginal portion by any convenient means. The most feasible is by coating the upper side 0i the marginal portion 4 with a layer of adhesive, such as latex, and pressing the overlapping portions to gether. Since the strips; are generally very long,

this` isA preferably accomplished by passing the stripslongtudinally through a. pair of rollers to force the adjacent'. portions 'into close contact while the adhesive is permitted to dry or set.

In order tov make an even more desirable and lessvisible joint, it is preferred. to form the; rows 2A of pile on the overlapping edge of the strip slightly shorter than the remaining rows, or a distance equal to approximately the width of the backing. sheets. Thus in Fig. 2, the rowsY indi.- cated as 2A are formedi in this manner so that allV tufts. 3 terminate in substantially vthe same horizontal plane. This particular improvement can, of course, be` utilized in present and conventional joining structures.

ToI iinish the strips or the completed rug, the underside may be coated with a layer of latex which serves two purposes. First' ofV all, it tends to bind the pile material tothe backing sheet and prevents its being pulled outfrom the upper side; and secondly, it provides` a flexible, frictional surfacewhich tends to keep the rug from slipping.

From the above, it is obvious that the invention provides a looped pile rug which is exceed,-

ingly easy to manufacture' and eliminates, to a large extent, the, unsightliness of the joints, even after longA use. It provides an inexpensive way ofv joiningr strips tov form rugs of any desired width, byusing any desired number ofl strips'. The'. extra. marginal edge can, of course, lbe cut off as desired to nish the completed rug.
